Step 3) profit

 

my boy pulled a code nd it was a vtec problem but couldnt figure out wat is causing it?

 

Well, lets start off by you giving us all the details you can.
What mods are done to the car?
When did it start doing this?
What codes did you pull? Need to know them all if you want us to be able to help.

check ^^ out. See what code you got.

 

Is the code 22 vtec pressure valve

 

Code 22 is most likely caused by low oil pressure which could be from a few different things. Lack of oil, bad oil pump or clogged strainer/pickup, screen on VTEC solenoid clogged. Also damage to the wiring could cause it to not engage, though from you description of it only happening in 4/5th.

Start off by verifying you have the proper amount of oil.
Next remove the VTEC solenoid and clean it
Remove bolts, spray liberally with brake kleen or similar product. Replace gasket, I think its around $5 from Honda.

Next I would verify continuity at the harness.

This is again for a Prelude but similar

If all this checks out then replace your VTEC solenoid with a new one or a working unit barrowed from a friend. Lastly, I would suspect oil pump or pickup tube problems. In which case, you would need to remove the oil pan and inspect for damage/problems.

Hope this helps - SA

 

i recently did a oil change and is not leaking so i dont think is that? but is weird how 4th and 5th dont pass 5000 rpm at all and wen i try passing 5000 rpm in 4th gear it wont let me it will **** back and after that happens in any gear u cant hit pass 5000 rpm? but then i turn off the viechle and then 1st 2nd and 3rd start to work again? so its weird?

 

The CEL is triggering your ECU to go into "Limp mode". This will restrict the vehicle from accelerating past 5k rpms and possibly damaging itself. Have you removed the VTEC Solenoid yet to verify its clean and not obstructed? Checked the wiring for any damage/breaks?
